Gene, it looks just like a ZID K55, google that and see what pops up----- ORIGINAL MESSAGE FOLLOWS ----- This is the Russian hummer that didn't sell on ebay. I acquired it. It's an interesting little bike. I've been told by a few eastern block antique motorcycle museums that it may be the only one in the USA.It is a 1954(?) Kovrov Arms Factory K-125.There were at least 3 companies in Russiaa that made. Lines of the DKW RT 125. Mockba, Minsk, and Kovrov Arms Factory. Mockba was acquired by Minsk at some time. Apparently the kovrov arms factory bikes are the rarest of the three. Does anyone know anything about this? Research has been difficult at best! Thanks in advance. Gene
